 Points of Attention

Environment

1. DO NOT install the PLC in a dusty, smoky, or corrosive atmosphere.

2. DO NOT install the PLC in an environment with high temperature or high condensation.

3. DO NOT install the PLC in an environment with immediate vibration and shock.

Construction

1. Any accident the drop of conductive debris into the PLC during screwing and wiring has to be avoided.

2. Allow a minimum space of 50mm between PLC and other control components, and keep PLC away from

the high-voltage lines or any power equipment.

4.3 Wiring and Specifications of the Power Terminals

This PLC model uses DC input power. Therefore, make sure that PLC is connected to terminals 24VDC and

0V (power range 20.4VDC~28.8VDC) when the power is ON. PLC will stop the operation and output will be

OFF whenever the power input is lower than 20.4VDC. Consequently, the ERROR LED will blink swiftly.

Overload Capacity of the Output Terminal

Every output contact possesses the overload capacity that is twice the rated current within 5 minutes, and as

for the common contact, the overload capacity is 1.5 times the rated current within 2 minutes. And if the

range is exceeded, it might result in the contact’s malfunctioning, or even cause internal wire burnt.

There are two types of output modules for the DVP-S Series PLC: relay or transistor. Refer to Functions &

Since the transistor module output is an Open Collector output, and if Y0 is

TRIAL RUN

 Power Indication

1. At the front of the MPU or the expansion unit, there is a “POWER” LED. When the MPU is powered ON, the

LED (in green) will be ON. If the indicator is not on when the MPU is powered up, it means there is problem

that DC power supplies to PLC. Thus, it is important to check whether the wiring of +24V and 0V are properly

conducted. If ERROR LED is blinking swiftly, it means +24VDC does not supply enough power to PLC.

2. If the other indicator, “L. V”, that locates at the front of the extension unit is on, it means that the input power

voltage to the extension unit is insufficient, and the output from the extension unit should be prohibited.

 Preparation

1. Make sure that the power wiring and the I/O wiring are both conducted properly before the power ON. Please

ensure NOT supply AC110V or AC220V to the I/O terminals, or the wiring might be short circuit which would

damage the PLC directly.

2. After using the peripheral devices to write the program into the MPU and that the ERROR LED of the MPU is

not on, it means that the program in use is legitimate, and it is now waiting for the user to give the RUN

command.

3. Use HPP to execute the forced On/Off test of the output contact.

 Operation & Test

1. If the ERROR LED of the MPU is not blinking, use the peripheral device to give the RUN command, and the

RUN indicator will then be on.

2. HPP could be utilized to monitor the settings and the registered values of the timer, the counter and the data

LED is on (but not blinking), it means that the setting of the user’s program has exceeded the preset time-out

limit. At this case, please turn the PLC RUN/STOP switch to STOP, and find out the address of the time-out

program by special data register D1008. ”WDT” instruction can be used to solve the problem.

 The PLC I/O Response Time:

The total response time of the PLC from the input signal to the output motion is calculated as follows:

“Response Time” = “input interface delay time” + “user’s program scan time” + “output motion delay time”

Input interface delay time

Factory setting: 10ms. Please refer to the usage of special registers

D1020~1021.

User’s program scan time Refer to the usage on special register D1010 for detail.

Output motion delay time The relay module is about 10ms. The transistor module is about 20~30μs.

 Basic Commands and Application Commands of the PLC:

◎ The basic commands and the application commands of the MPU of this series are totally applicable to the

DELTA DVP-PLC ES Series MPU. Refer to the DELTA PLC Technique Application Manual for relevant basic

commands and application commands.

◎ The DVPHPP hand-held programming panel, the DPLSoft (the DOS version) ladder diagram editing program

or the WPLSoft (the Windows version) ladder diagram editing program are all good for use with the DELTA

DVP-PLC, also the PLC could connect with the DVP14SS MPU through specific transmission wire, and then,

the program transmission, the MPU control and the program monitoring could all be executed.

6 FAULT CHECK & MAINTENANCE

6.1 Judge the Error through the Indicator at the Front Panel

When error occurred for the DVP PLC, please check:

“POWER” LED

There is a “POWER” LED at the front of the MPU. When the MPU is powered On, the green LED light will be

on. If the indicator is not on when the MPU is powered up and with the input power being normal, it is an

indication that the PLC is out of order. Please have this machine replaced or have it repaired at a dealer near

you.

“RUN” LED

Identify the status of the PLC. When the PLC is in operation, this light will be on, and users could thus use

HPP or the ladder diagram to edit program and give commands to make the PLC “RUN” or “STOP”.

“ERROR” LED

1. If illegitimate program is input to the MPU, or that the commands and devices of the program exceed the

allowable range, the indicator will thus be blinking. In this case, the user should inquire about the error

code from the special data register D1004 in the MPU and look it up in the Error Code Table. After the

error is found and the program is revised, send the revised version to the MPU.

2. If the PLC is unable to perform function, and the LED is blinking swiftly, it indicates that 24VDC power

does not supply sufficient power. Please check whether the power supply of 24VDC is normal or not.

3. When the ERROR LED is on (not blinking), it is an indication that the execution time of the program

circuit has exceeded the preset time-out limit (setting of D1000). To check the program circuit or use the

WDT command to improve the error status. Once program modification is completed, user can

re-download the program of PLC and the ERROR LED will be off. If the ERROR LED is still keep on,

please turn off the power and check if there’s any noise or any conductive invader inside the PLC.

“Input” LED

The On/Off signals of the input point could be displayed through the “Input” LED, or monitor the status of the

input point through the device HPP monitoring function. Once the motion of the input point is valid, the LED is on.

Therefore, if errors are detected via using HPP, the LED and the input signal circuits then are used to check

whether the status is normal. Especially when the electronic switch of great electric leakage is utilized, the input

point is usually witnessed with unexpected motions.

“Output” LED

The “Output” LED is designed mainly for display the On/Off status of the output signals. When the “Output” LED

is On or Off and that the loading is of an opposite motion, the following conditions should be attended to:

1. The output contact might be melted down and blocked up due to overload or load in short-circuit, defect

happened consequently under this situation.

2. If the output contact is function as undesired, be sure to check the output wiring circuit and whether the

screw is tightened or not.

6.3 Periodic Inspection

Since the DVP series PLC does not utilize disposable components, there is thus no need to replace most of the

components. However, if the output relay turns on/off frequently, or drive the large load current too often, life of

the output contact will thus be decreased. Under a condition like this, periodic inspection is then needed to

ensure if the contact is of the “Permanently Open” status or of the short-circuit status. Moreover, the following

precautions should be noted:

1. Do not mount the DVP under direct sunlight or near any heat-radiation objects.

2. Do not install the DVP-PLC in places subject to high temperature, high humidity, excessive vibration,

corrosive gasses, liquids, airborne dust and metallic particles.

3. Check periodically whether the wiring and terminals are tightened and conducted properly.
